定點式應變傳感光纜
Point Style Strain Sensing Cable
產品描述Description
定點式應變傳感光纜是一種專業BOTDR和BOTDA原理研究的一種應力、應變傳感光纜，光纜由中心的緊包型應變傳感光纖+鎧裝保護層+熱塑性外護套組成。光纖與鎧裝層處于自由活動狀態,再通過一定間距對應力傳感光纖與鎧裝層和外護套進行固定,從而實現空間非連續非均勻的分段,應變測量結果可直接進行位移量的計算
Fixed-point strain sensing optical cable is a kind of stress and strain sensing optical cable which designed for BOTDR and BOTDA sensing system. The optical cable is composed of the compact strain sensing optical fiber in the center, armored protective layer and thermoplastic outer sheath. T The optical fibers are interactively fixed in the armored tube by a certain distance, which device the cable to several distances to monitor.
產品特點Features：
通過間隔地固定光纖以實現光纜的分區測量；To divide the cable to several detective distance through the interval fixed partition of fiber
分區點可見，便于固定安裝；The fixed point is easy to install.
應變光纖可以選用不同類型的光纖；The strain sensing fiber can be chosen
應變光纖被鎧裝鋼管保護，可適合各種惡劣環境The fiber is protected by the armored tube, which make the cable suitable for various application environment.
